BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a protecting case; and more particularly to a protecting case for a mobile phone.

2. Description of the Prior Art

Various protecting cases for mobile phones are developed for protecting mobile phones against abrasion and drop, preventing the product external appearance, use performance and service life from deteriorating.

Among numerous protecting methods and protecting apparatuses, there is a fashion and popular method to protect the mobile by covering the periphery of the mobile phone with a hard or soft sleeve, particularly the side edges and the angles (of the mobile) that are most likely to be scratched can be protected. The sleeves are mostly integrally-formed hard or soft rubber products, so that they cannot abut against the mobile phone to be protected closely, adversely affecting the appearance of the mobile phone.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a protecting case which can be closely fitted on the mobile phone into an integral structure.

To achieve the above objective, a protecting case in accordance with the present invention comprises an upper protecting element and a lower protecting element that are both in the form of a hollow frame.

The upper protecting element includes a rectangular upper engaging portion around a top thereof in such a manner that a top opening of the upper protecting element is smaller than a bottom opening of the upper protecting element, adjacent to the bottom opening of the upper protecting element is annularly provided a groove around an inner periphery of the upper protecting element, the upper protecting element is engaged on a to-be-protected product through the bottom opening of the upper protecting element in such a manner that the upper engaging portion of the upper protecting element is closely fitted on a top outer periphery of the to-be-protected product.

The lower protecting element includes a rectangular lower engaging portion around a bottom thereof in such a manner that a bottom opening of the lower protecting element is smaller than a top opening of the lower protecting element, adjacent to the top opening of the lower protecting element is annularly provided a rib protruding from an outer periphery of the lower protecting element. The lower protecting element is engaged at a bottom of the to-be-protected product through the top opening of the lower protecting element in such a manner that the lower engaging portion of the lower protecting element is engaged on a bottom outer periphery of the to-be-protected product while the rib is engaged into the groove of the upper protecting element.

The upper engaging portion of the upper protecting element is formed with a stepped frame body around the top thereof, and the frame body has an arc surface to be fitted on an arc surface formed on a top circumference of an upper portion of the to-be-protected product.

The whole lower protecting element is located at the lower portion of the to-be-protected product for fitting on the lower portion of the to-be-protected product.

Alternatively, the bottom opening of the lower protecting element is formed as a closed solid structure.

The upper and the lower protecting elements of the protecting case are made of hard rubber or metal, and the upper protecting element is further formed with at least one key hole to be aligned with keys on the to-be-protected product.

A top outer edge of the upper protecting element takes the form of a chamfered edge, a right-angle edge or a rounded edge.

A bottom outer edge of the upper protecting element takes the form of a chambered edge, a right-angle edge or a rounded edge.

Besides the side edges and the angles of the to-be-protected product, the protecting case of the present invention can also protect the whole bottom surface of the to-be-protected product. Furthermore, other uncovered portion can also be protected by the upper protecting element and the lower protecting element against damage, scratch or wear. The upper protecting element is formed with the key holes to be aligned with the keys on the to-be-protected product, increasing the use convenience. Since the upper and the lower protecting elements are made of the hard rubber or metal, the protecting case may not affect the normal use of the to-be-protected product and make the protected product have the same hand feel as the product which is not protected by the protecting case, increasing convenience in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIGS. 1-10, a protecting case in accordance with a preferred embodiment of the present invention comprises an upper protecting element 1 and a lower protecting element 2. The upper protecting element 1 is in the form of a hollow frame and includes a rectangular upper engaging portion 11 and a stepped frame body 13 around a top thereof in such a manner that a top opening 111 is smaller than a bottom opening 112. Adjacent to the bottom opening 112 is annularly provided a groove 12 around an inner periphery of the upper protecting element 1. The upper protecting element 1 is engaged on a to-be-protected product 3 through the bottom opening 112 in such a manner that the upper engaging portion 11 can be closely fitted on the top outer periphery of the to-be-protected product 3. The stepped frame body 13 of the upper protecting element 1 is formed with an arc surface to be fitted on an arc surface formed on a top circumference of an upper portion 31 of the to-be-protected product 3.

The lower protecting element 2 is in the form of a hollow frame and includes a rectangular lower engaging portion 22 around a bottom thereof in such a manner that a bottom opening 221 is smaller than a top opening 222. Adjacent to the top opening 222 is annularly provided a rib 21 protruding from an outer periphery of the lower protecting element 2. The lower protecting element 2 is engaged at the bottom of the to-be-protected product 3 through the top opening 222 in such a manner that the lower engaging portion 22 can be engaged on a bottom outer periphery of the to-be-protected product 3 while the rib 21 is engaged into the groove 12 of the upper protecting element 1. In other words, the upper and the lower protecting elements 1, 2 are engaged to each other through the groove 12 and the rib 21, and the upper and the lower protecting elements 1, 2 can be closely engaged on the to-be-protected product 3 to form an integral structure. Since the whole lower protecting element 2 is located at the lower portion 32 of the to-be-protected product 3, after the protecting case in accordance with the present invention is engaged on the to-be-protected product 3, it can protect the side edges and angles of the to-be-protected product 3 without affecting the appearance of the to-be-protected product 3.
